Running OpenFAST on High Performance Computer (HPC)

Dear @Jason.Jonkman,

I am planning to construct fragility curves for the 5 MW barge-type FOWT. This task demands a lot of simulations which means thousands of calls of OpenFAST.

I started recently to use HPC (High Performance Computer). I am just testing right now. OpenFAST v3.5.3 was installed. I launched OpenFAST like on my laptop (i.e. using cmd).

OpenFAST exits with errors.

FAST_InitializeAll:HydroDyn_Init:Waves_Init:VariousWaves_Init: The random number generator in use** differs from the original code provided by NREL. This pRNG uses 33 seeds instead of the 2 in the**** HydroDyn input file.**
** FAST_InitializeAll:SrvD_Init:BladedInterface_Init:The dynamic library ./Discon_ITIBarge.dll could**** not be loaded. Check that the file exists in the specified location and that it is compiled for**** 64-bit applications.**

For the second error, i am sure that the .dll is placed in the right place and the correct path is given to ServoDyn.

Could you please help me solving them ?

Best Regards,

Riad

Dear @Riad.Elhamoud,

The statement about the random number generator is just a warning, not an error.

The error about the DLL could not being loaded is the issue. This question has been discussed on the forum before. In your case, presumably your HPC is not Windows based, in which case the controller dynamic library must be compiled as a shared object (.so) rather than as a .dll.

Best regards,
